A Storm 5 Alert was issued Wednesday night into Thursday morning for Tennessee and Kentucky.
Heavy rainfall caused water levels to rise in many creeks and rivers that were already at high levels due to so much rain in the past week.
The first round of rain moved through the region Wednesday morning, and another round hit the area later Wednesday night.
While there will be 1-3'' of rain in some northern counties, the biggest threat will be to the south. Lawrenceburg has already received up 3'' of rain, and some southern counties could see 4-6'' of rain total, adding to existing high waters.
A Flood Watch was issued Wednesday afternoon to noon Thursday for rivers and streams. Localized flash flooding was also expected.
NewsChannel 5's Lelan Statom said most of the impact will be seen in low-lying areas, especially those spots that flood easily.
Thunderstorms were possible, but the biggest threat in this weather event was expected to be flooding.
The rain has been expected to stop Thursday afternoon and evening, making way for a dry weekend. Saturday could be the first Saturday in six weeks without measurable rainfall in Nashville.
Unfortunately, the dry weekend will be followed up by another chance for more rain on Monday and Tuesday.
The flooding also prompted a boil water advisory in Centerville. Officials there said they had reason to believe the flood water caused water distributed to customers to possibly be contaminated. They've been asked to strain the water through a clean cloth prior to boiling it. It should be heated to a "vigorous boil" for one minute.
